A stage worker was slightly injured by a falling piece of scenery in the Bolshoi Theater, which reopened on Friday after extensive six-year renovation, a police source said. \"A stage worker was injured, he received a chest contusion and was hospitalized,\" the source said. The cause of the incident is being established. The Bolshoi Theater, one of the main landmarks of the Russian capital and a symbol of Russian culture, reopened on Friday after six years of reconstruction with a gala concert attended by members of the Russian and international beau monde. The theater, built in 1825, closed for reconstruction in 2005. The reconstruction was initially scheduled for completion in 2008, but the project has been marred by repeated delays as well as a misappropriation scandal. The Russian government spent 21 billion rubles ($681 million) on the restoration, which involved more than 3,600 designers, builders and engineers.
